lMPROVEMENT IN SHEET-METAL HAMES.

Specification forming part of Letters Patent No. 221,211, dated November 4, 1879; application tiled i May 26, 1879.

To all whom it may concern: i

Be it known that I, JOHN S. BROWN, of Galveston, in the State of Texas, have invented an Improvement in Sheet-Metal Eames, of' which the following is a specification.

Haines for horse-collars are usually of wroughtdron forged `up to shape, and provided with eyes or tugs, either riveted to place or brazed or welded upon the hame. These hames do not take an even bearing upon the collar, they are expensive, and areliable to be easily broken, and usually the chains rnb against the collar and wear the saine.

My improvement relates to' a llame made of sheet metall, cut out of' a width that varies in the different parts, so as to be of proportionate strength throughout, and the hame is curved baokwardly at the sides where the traces are connected, so as to take an extended bearing on the surface ot the collar and' prevent the same becoming attened or worn by the chains or traces.

In the drawings, Figure l is an elevation of the haines as applied upon a collar, the-front part of the collar, at one side, being removed. Fig. 2 is a horizontal section of tLe collar and hames.

The collar "a is of any usual or desired char-- acter, as my improved llames may be usedV with any collar or pads.. 4

The haines are cut out of sheet metal. The top part ot".` each hame is curved, as at c, and provided with slots for the strap d or other device that connects the upper ends together. There is a slot or morti'se, c, at the lower end of each hame for the connecting-strap f.

The outline of the inner edge ofeach haine is ofthe ordinary shape, and the same is adapted to the grooved exterior surface of the colL lar. The sheet metal, however, is of varying' widths and thickness, according to the strain f upon the hames, that part where the traces h are the hooks for the traces or trace-chains. These hooks will usually be made of a sheetmetal tongue cut from the metal ot' the haine and bent outwardly and forwardly, as shown in Fig. 2, and a springjaw, i', may be used similar to that in a snap-hook, or else the hook h may be a separate piece and riveted or oth erwise attached upon the sheetmetal, as illustrated in Fig. 1 by dotted lines.

' The sheet metal is curved backwardly, as shown in Fig. 2, to stiften the same, and also to cause the hame to take a proper bearing upon the collar, so as to avoid the wear that is usual with the ordinary haines. The edges ot the llames may be stiftened by bending the sheet metal in the form of a flange or rib.

The rings or eyes a for the reins are preferably cnt out of the sheet metal of the llame; but they may be separate and attached by rivets or otherwise.

These sheet-metal hainesv are by preference tinned or galvanized to protect the same from rust. They may also be japauned, painted, or left without any coating.

I am aware that llames have been made of sheet' metal and wood combined, the sheet JOHN S. BROWN.
